TRIPOLI/LONDON (Reuters) Libyan warplanes were bombing indiscriminately across Tripoli on Monday as Muammar Gaddafis four-decade-old rule appeared in increasing jeopardy when days of anti-government protests reached the capital for the first time and security forces killed at least 160 people. A resident of the Libyan capital told Al Jazeera television in a live broadcast What we are witnessing today is unimaginable. Warplanes and helicopters are indiscriminately bombing one area after another. There are many, many dead, Adel Mohamed Saleh said. Saleh, who called himself a political activist, said the bombings had initially targeted a funeral procession. Our people are dying. It is the policy of scorched earth. he said. Every 20 minutes they are bombing. Asked if the attacks were still happening he said: It is continuing, it is continuing. Anyone who moves, even if they are in their car they will hit you. There was no independent verification of the report but Fathi al-Warfali, the Libyan activist who heads the Swiss-based Libyan Committee for Truth and Justice, who was taking part in a protest outside UN European headquarters in Geneva said he had heard the same reports.Military planes are attacking civilians, protesters in Tripoli now. The civilians are frightened. Where is the United Nations, where is Amnesty International? al-Warfali told Reuters. No independent verification of the report was immediately available. Two Libyan Air Force fighter pilots defected on Monday and flew their jets to Malta where they told authorities they had been ordered to bomb protesters, Maltese government officials said. They said the two pilots, both colonels, took off from a base near Tripoli. One of them has requested political asylum.The pilots are being questioned by the Maltese police. The two said they decided to fly to Malta after being ordered to bomb anti-government protesters in Libyas second largest city of Benghazi, the sources said. Clashes in the Libyan capital Tripoli on Monday have left 160 people dead, Arabiya television quoted eyewitnesses as saying. The Arab satellite channel gave the number in a newsflash, without providing further details. Residents said several cities in the east appeared to be in the hands of the opposition as protests spread from Benghazi, the cradle of a popular uprising that threatens to overthrow one of the Arab worlds most entrenched governments. One of Gaddafis sons said the veteran leader would fight the revolt until the last man standing. Protesters rallied in Tripolis streets, tribal and religious leaders spoke out against Gaddafi, and army units defected to the opposition in a revolt that has cost the lives of more than 200 people. Some analysts suggested Libya was heading for civil war. Libya is the most likely candidate for civil war because the government has lost control over part of its own territory, said Shadi Hamid, director of research at the Brookings Doha Centre in Qatar. Output at one of Libyas oil fields was reported to have been stopped by a workers strike and some European oil companies withdrew expatriate workers and suspended operations. Most of Libyas oil fields are in the east, south of Benghazi. Anti-government protests have also broken out in the central town of Ras Lanuf, the site of an oil refinery and petrochemical complex, Libyas Quryna newspaper said on its website Monday. A Libyan man, Soula al-Balaazi, who said he was an opposition activist, told the network by telephone that Libyan air force warplanes had bombed some locations in Tripoli. An analyst for London-based consultancy Control Risks said that indicated the end was approaching for Gaddafi. These really seem to be last, desperate acts. If youre bombing your own capital, its really hard to see how you can survive, said Julien Barnes-Dacey, Control Risks Middle East analyst. Meanwhile, Telegraph quoting credible Western intelligence reports said on Monday that Muammar Gaddafi had fled Libya and was on his way to exile in Venezuela, according to William Hague, the foreign secretary. William Hague said he had seen information to suggest Gaddafi had fled Libya and was on his way to the South American oil-exporting nation. However, the government of President Hugo Chavez denied reports Gaddafi was travelling to Venezuela following violent protests. In signs of disagreement inside Libyas ruling elite, the justice minister resigned in protest at the excessive use of violence against protesters. In India, Libyas ambassador said he was resigning in protest at the violent crackdown. There was no immediate word on Kaddafis location. European nations watched developments in Libya with a growing sense of alarm after the government in Tripoli said it would suspend cooperation on stemming the flow of illegal immigrants across the Mediterranean. The building where the General Peoples Congress, or parliament, meets in Tripoli was on fire Monday, as was a police station in one of the eastern suburbs. Al Jazeera television quoted medical sources as saying 61 people had been killed in the latest protests in Tripoli. The violence flared overnight, and witnesses said gunfire was heard across the city in the early morning. Government forces appeared to regain control of the central Green Square by midday Monday, according to the BBC. Citing witnesses in Tripoli, the network said protesters had besieged the building that houses state-run TV and forced at least one channel off the air. It said security forces were looting banks and other government institutions in Tripoli, and protesters had broken into several police stations and wrecked them. A Reuters reporter in Tripoli said there were long queues for food and fuel as residents stocked up on essential goods, apparently anticipating new clashes after nightfall. Gaddafis son Saif al-Islam Gaddafi appeared on national television Sunday night in an attempt both to threaten and to calm people, saying the army would enforce security at any price to put down the revolt. We will keep fighting until the last man standing, even to the last woman standing, he said Sunday. He warned of an impending civil war and said the country had reached a critical crossroads. He denied rumours that his father had fled the country, saying only that Gaddafi was still in Libya. The younger Kaddafi said the military had made mistakes in confronting demonstrators but would remain loyal. He blamed the unrest on foreigners, Islamists and criminals whom he accused of plunging the country into civil war and threatening to destroy its oil wealth. But people in Tripoli expressed anger at the speech. Gaddafi supporters were in central Tripolis Green Square on Monday, waving flags and carrying his portrait. Saif al-Islams cajoling is unlikely to be enough to douse the anger unleashed after four decades of rule by Gaddafi - mirroring events in Egypt where a popular revolt overthrew the seemingly impregnable President Hosni Mubarak 10 days ago. In the eastern city of Benghazi, protesters appeared to be largely in control after bloody clashes with troops and police. Youths with weapons are in charge of the city. There are no security forces anywhere, University of Benghazi professor Hanaa Elgallal told Al Jazeera International television. Salahuddin Abdullah, a self-described protest organiser, said: In Benghazi there is celebration and euphoria...The city is no longer under military control. It is completely under demonstrators control. There were reports that soldiers who refused to fire on civilians were executed by commanding officers in Benghazi. We have buried today 11 bodies of soldiers who refused to fire on civilians and were executed by Gaddafi officers. The bodies were cut, heads in one side and legs in the other...it is a crime what is happening here, said Elsanous Ali Eldorsi, a retired judge in Benghazi. At least nine towns in the east, including Benghazi, Zuara and Zlitan, were under the control of protesters loyal to tribal groups, the president of the International Federation for Human Rights in France told Reuters. Human Rights Watch said at least 233 people had been killed in five days of violence, but opposition groups put the figure much higher. Most were in Benghazi, a region where Gaddafis grip has always been weaker than elsewhere. Support for Gaddafi, who seized power in 1969, among Libyas desert tribes was also waning. The leader of the Al-Zuwayya tribe in the east threatened to cut oil exports unless authorities halted oppression of protesters. Meanwhile, Yemeni President Ali Abdullah Saleh said Monday only defeat at the ballot box will make him quit, even as MPs joined thousands of protesters in Sanaa calling for his departure. In the countrys south, police shot dead a protester in the regional capital, Aden, where protests have raged killing 12 people and wounding dozens since February 16, medics and witnesses said. If they want me to quit, I will only leave through the ballot box, Saleh told a news conference as the protesters, including opposition MPs, gathered outside Sanaa University. The opposition are raising the level of their demands, some of which are illicit, the Yemeni leader said. Saleh, whose long reign makes him one of the Middle Easts great survivors, said the protests were not new, accusing his opponents of having been behind the demonstrations for a while. Opposition MPs, who vowed to take to the streets in a statement issued on Sunday, joined students who have been protesting for the past nine days. Security forces surrounded the protesters as they gathered in a nearby square carrying banners declaring: People want change, People want to overthrow the regime and Leave. Plans by an exiled Shia leader to return home raised the stakes in a power struggle in Sunni-ruled Bahrain on Monda as protesters camped out in Manamas Pearl Square pressed demands for a new government on Monday, backed by a teachers strike that closed many schools. No teaching until the government falls, chanted more than 1,500 teachers gathered at the square in the Bahraini capital. Up to 10,000 demonstrators packed Pearl Square, at the heart of week-long protests led by majority Shias demanding more say in the Sunni-ruled kingdom, a close US and Saudi ally. Near the group of teachers, a dangerously leaning chair had been erected, representing the government, on top of a box painted blood-red. Arrows were stuck into the chair, which had a rifle strapped to it. They bore labels such as corruption, joblessness, naturalisation and the blood of martyrs. The opposition is demanding a true constitutional monarchy that gives citizens a greater role in a directly elected government. It also wants the release of political prisoners. King Hamad bin Isa al-Khalifa has asked his son, the crown prince, to conduct a dialogue with all parties, but after the bloodshed on the streets, opposition parties are wary. Five bodies were found in a bank set ablaze in Morocco on the sidelines of one of many demonstrations calling for change around the country, the interior ministry said on Monday. Some 128 people, mostly security officers, were injured and 120 people were arrested in unrest on Sunday following demonstrations that drew around 37,000 Moroccans in dozens of cities and towns, according to Interior Minister Taib Cherkaoui. Protesters were demanding King Mohammed give up some powers, dismiss the government and clamp down on corruption. The charred bodies were found in a bank in the northern town of Hoceima. Cherkaoui said shops, public institutions, banks and cars had been damaged in various cities hit by the unrest. Some troublemakers forced their way into a customs building and stole drugs and alcohol, Cherkaoui said. He said 120 people had been arrested.
